Description :
Usage Introduction
Mainly used in the production of polyester, polyester resin, moisture absorbing agent, plasticizer, surfactant, synthetic fiber, cosmetics, and as a solvent for dyes/inks, antifreeze agent for engine formulation, gas dehydrating agent, resin manufacturing, and also as a wetting agent for glass paper, fibers, leather, adhesives. It can produce synthetic resin PET, fiber grade PET (polyester fiber), and bottle grade PET for making mineral water bottles, etc. It can also produce alkyd resin, formaldehyde, etc., and is also used as an antifreeze agent. In addition to being used as an antifreeze for automobiles, it is also used for the transportation of industrial cooling capacity and is generally referred to as a refrigerant carrier.
When using ethylene glycol as a refrigerant, attention should be paid to:
1. Its freezing point changes with the concentration of ethylene glycol in aqueous solution. When the concentration is below 60%, the concentration of ethylene glycol in the aqueous solution increases and the freezing point decreases. However, when the concentration exceeds 60%, the freezing point shows an upward trend with the increase of ethylene glycol concentration, and the viscosity also increases with the increase of concentration. When the concentration reaches 99.9%, its freezing point rises to -13.2 ℃, which is an important reason why concentrated antifreeze (antifreeze mother liquor) cannot be used directly and must be noted by users.
2. Ethylene glycol contains hydroxyl groups and works at 80-90 degrees Celsius for a long time. Ethylene glycol is first oxidized to glycolic acid, and then oxidized to oxalic acid, which contains two carboxyl groups. Oxalic acid and its by-products first affect the central nervous system, followed by the heart, and then the kidneys. Without proper treatment, excessive intake of ethylene glycol can lead to death. Ethylene glycol oxalic acid causes corrosion and leakage of equipment. Therefore, in the prepared antifreeze, preservatives must also be present to prevent corrosion of steel and aluminum and the formation of scale.
